Habitat

Most smaller leatherjacket species prefer estuary and harbour habitats with plenty of weed and reef cover. Larger species are more likely encountered in offshore waters ranging from 5 – 500 meters in depth.  Wharves, rock walls, jetties and wrecks are always a great place to find leatherjacket as they shelter from predators and feed on the many food sources found in the area. Leatheries can also be found roaming the deep, blue oceans in extreme depths of over 200 meters or more, these are pelagic Chinaman and Unicorn leatherjacket and are considered to be a nuisance by most anglers and have an infamous reputation for biting through main lines and leaders.

Tackle requirements

Ultra light and light graphite spin rods 6’6” – 7’ in length that will cope with gel spun, nylon and braided lines rated from 2 – 4kg are ideally suited to targeting leatherjacket and when coupled with quality spin reels in the 1000 – 2500 class make excellent combos. Larger outfits spooled with heavier 10 – 12lb nylon line can also be used when targeting larger fish around heavy cover. Longer rods 8’ to 10’ in length and spin or over head reels loaded with nylon lines around 4 – 6kg are preferred for targeting leatherjacket at most coastal rock locations around Australia. Fluoro carbon leaders with breaking strains of  6 – 15lb should also be joined to mainlines via an improved albrite knot and not only prevent the fish from seeing your brightly coloured main line but
also help from being chaffed of on rough underwater structures.

Recommended baits, lures and rigs

Small, cut pieces of prawn, blood worm, and small bait fish such as mullet, mackerel and pilchards are all ideal bait options for chasing leatherjacket and should be fished on a long shank pattern of hook to avoid bite offs and allow for easy removal.

Handy hints and tips

Try rubbing a couple of drops of aniseed oil on your hands before commencing fishing, this will encourage shy fish to actively feed and is considered to be illegal in some countries due to its efficiency for attracting fish. Always fish as light as possible for leatherjacket this includes sinkers, lines and leaders. Long shank hooks will help to prevent bite offs and are much easier to remove!

Preferred fishing times and tides

Most fish species including leatherjacket prefer rising tides and low light periods such as dawn or dusk but will also actively feed during most stages throughout the day and night depending on tidal movement and of course location.
